Description
Stage 1 ECU Tune – Infiniti G37 (2009–2013)
Typical Dyno Results
- Power: 321 HP → 340 HP (Up to +19 HP)
- Torque: 266 lb-ft → 280 lb-ft (Up to +15 lb-ft)
- Biggest torque gains from 1,700–2,700 RPM – improved throttle response and low-end pull
What’s Included
- Top speed limiter (V-Max) removed
- Adjusted max torque limiters
- Improved ignition timing
- Optimized air-fuel ratio at wide open throttle
- Reduced torque management intervention
- Optional lambda off available for headers and/or hi-flow cats
This tune is safe for stock or full bolt-on G37s with intake, headers, and cat-back exhaust—as long as the air inlet tube diameter around the MAF sensor is the same size as stock.

UpRev Alternative
This is a simplified, lower-cost solution for bolt-on or stock G37s. We are not trying to compete with UpRev. UpRev supports advanced mods like forced induction, map switching, launch control, and other premium features. If you need that level of tuning, UpRev is the better (and more expensive) option.
We do not support switchable tunes or boosted builds. Our focus is delivering clean, reliable, budget-friendly tuning for daily-driven or lightly modified G37s.
